hi!!

I have a data in 2x2, whose cell counts may be close
to zero; The calculation of odds ratio fails and conf.
interval cannot be determined. Is there an exact
logistic (as in SAS) kind of procedure which can give
me the conf. interval and an estimate for the single
parameter model ?

many thanks,
Jag
